A solvent dye is a dye soluble in organic solvents. It is usually used as a solution in an organic solvent. Solvent dyes are used to color organic solvents, hydrocarbon fuels, waxes, lubricants, plastics, and other hydrocarbon-based nonpolar materials. Fuel dyes are one use of solvent dyes. Their molecules are typically nonpolar or little polar, and they do not undergo ionization. They are insoluble in water. They form a colloidal solution in solvents. They have poor (basic dyes) to good (metal complex based) light fastness.

Colored polyurethane resin for synthetic leather and preparation method thereof
The invention relates to the technical field of materials for a synthetic leather, and specifically relates to a colored polyurethane resin for the synthetic leather and a preparation method thereof. Provided is the colored polyurethane resin for the synthetic leather; the colored polyurethane resin is obtained by mainly preparing the raw materials as follows: a macromolecular polyhydric alcohol, a dye, a micromolecular polyhydric alcohol chain extender, diisocyanate, an accessory ingredient and a solvent. The dye is a dye containing di-hydroxyl or double primary amino groups. The colored polyurethane resin for the synthetic leather can be used for a polyurethane synthetic leather layer or a post-processing. Due to the fact that the dye molecules react on a polyurethane main chain, a phenomenon of color-transfer cannot happen, thereby solving the problem that the dye is easy to transfer after dyeing by a common polyurethane resin, and further solving the problem that the color is not bright and thorough enough caused by coloring the synthetic leather with pigments.
